What is the best way to check the reprocessing point in .net (C #)?

Question

My function is pretty much a standard search function ... I have included it below.

In the function, I have 1 line of code responsible for trimming the Repart NTFS points.

if (attributes.ToString().IndexOf("ReparsePoint") == -1) 

The problem is that I get the error Access to the path 'c:\System Volume Information' is denied.

I debugged the code, and only runtime attributes for this directory:

  System.IO.FileAttributes.Hidden | System.IO.FileAttributes.System | System.IO.FileAttributes.Directory 

I am executing this code on a Windows 2008 server machine, any ideas what I can do to cure this error?

 public void DirSearch(string sDir) { foreach (string d in Directory.GetDirectories(sDir)) { DirectoryInfo dInfo = new DirectoryInfo(d); FileAttributes attributes = dInfo.Attributes; if (attributes.ToString().IndexOf("ReparsePoint") == -1) { foreach (string f in Directory.GetFiles(d, searchString)) { //lstFilesFound.Items.Add(f); ListViewItem lvi; ListViewItem.ListViewSubItem lvsi; lvi = new ListViewItem(); lvi.Text = f; lvi.ImageIndex = 1; lvi.Tag = "tag"; lvsi = new ListViewItem.ListViewSubItem(); lvsi.Text = "sub bugger"; lvi.SubItems.Add(lvsi); lvsi = new ListViewItem.ListViewSubItem(); lvsi.Text = d;//"C:\\Users\\Administrator\\Downloads\\MediaMonkey.GOLD.EDITION.v.3.0.2.1134.[Darkside].[Demonoid].[Grim.Reaper]"; lvi.SubItems.Add(lvsi); listView1.Items.Add(lvi); } DirSearch(d); } } } 

Answer 1

No one has access to system volume information except for the SYSTEM account. Therefore, either change the directory permissions. Or it is much better to catch the exception and continue.

Answer 2

I'm not sure the answer to the question is, but please change your attribute check to use the correct bitwise operations!

 if (attributes.ToString().IndexOf("ReparsePoint") == -1) 

... much more correctly written as ...

 if ((attributes & FileAttributes.ReparsePoint) == 0)

A desperate decision is an attempt.
